Reference Guide
To disable PFC operation on an interface, enter the no pfc mode on command in 
DCB Input Policy Configuration mode. PFC is enabled and disabled as global DCB 
operation is enabled (dcb-enable) or disabled (no dcb-enable).
You cannot enable PFC and link-level flow control at the same time on an 
interface.
NOTE: Please note that Dell Networking does not recommended to use this 
command as it has been deprecated in the current 9.4(0.0) release. A warning 
message appears when you try to run this command indicating that you have 
to use the dcb-map commands in the future.
priority-group bandwidth pfc
Configure the ETS bandwidth allocation and PFC mode used to manage port traffic in an 802.1p priority 
group.
Syntax
priority-group group-num {bandwidth percentage| strict-
priority} pfc {on | off}
Parameters
priority-group 
group-num
Enter the keyword priority-group followed by the 
number of an 802.1p priority group. Use the priority-
pgid command to create the priority groups in a DCB map.
bandwidth 
percentage
Enter the keyword bandwidth followed by a bandwidth 
percentage allocated to the priority group. The range of valid 
values is 1 to 100. The sum of all allocated bandwidth 
percentages in priority groups in a DCB map must be 100%.

priority scheduling. Strict-priority traffic is serviced first, 
before bandwidth allocated to other priority groups is made 
available.
